Control Motor ECM3000 The ECM3000 is a control motor designed for various industrial equipment applications. Two models are available: 90° angular stroke motor for applications such as burner controls and 160° angular stroke motor for valve controls of hot and cold water or steam. Three kinds of control signal input types are available: relay contact, 4 to 20mAdc, and potentiometer. Three kinds of power supply voltage types are available: 24Vac, 100Vac and 200Vac. Additionally, a power supply unit applicable to a voltage range of 85 to 264Vac is also available for the 4 to 20mAdc input type. The ECM3000 contains a standard bracket accessory for retrofitting Yamatake’s older motors. ■ Features • Robust aluminum die-cast body. • Long life parts are used for the internal potentiometers and bearings of the motor. • Input is selectable - 3 input types. (According to model No.) Relay contact, 4 to 20mAdc and potentiometer. • The 90° angular stroke motor type has a pointer to indicate the position of the rotating shaft and a rotating direction label. • Four optional auxiliary switches are available with the 90° angular stroke motor type. ■ Specifications • For both 90° and 160° angular stroke motors, models with two auxiliary switches and open/close override function are also available. • Splash-proof structure IP54 or equivalent, superior to environment resistance. • Motor mounting bracket (standard accessory part) is compatible to replacing from Yamatake’s older motor being used at present. • Two angular strokes available for several applications. 90° type and 160° type • Output torque is 12.5N-m. • A CE-marked and cUL-certified product (24Vac model only). Note: * An auxiliary switch (4 units) can be built into the 90° stroke motor by specifying a model No. Code for in model No. 0: Auxiliary switch is not built in 1: Type with 4 auxiliary switches built in ** User can switch direct/reverse control action and adjust zero/ span and dead band. *** Position proportional operation + 2 auxiliary switches + open/ close override function **** Extension unit applicable later (T) Handling Precautions • The high-speed motor type must be used within a duty ratio (operation ratio) of 40%. • Do not connect the ECM3000F model to a mechanical balancing relay (R9107A, R927C, etc.). Doing so might damage the control motor by applying excessive voltage to its potentiometer.

|T| Handling Precautions • If an ECM3000F model controls the actuator on the basis of the resistance between T and G or between T and Y of the feedback potentiometer, it might not function normally, depending on the connected controller. For details, contact a Yamatake Corporation sales representative. • Be sure to apply non-voltage wiring to terminals S, CONT, CW, and CCW of ECM3000 models with an open/close override function. In some cases M744 and M7284 control motors take 24Vac to terminals S, CONT, CW, and CCW. If one of these models is replaced with an ECM3000 with open/close override...

■ Using a butterfly valve (V51E) If the ECM3000 is used with the V51E, mount the base kit (83165292-001, sold separately) between the V51E and the ECM3000. ■ Optional parts Name * Only one type of extension unit can be mounted on the model without internal auxiliary switch. ** The total resistance of the auxiliary potentiometer is 1kQ ± 10%. The output of the auxiliary potentiometer cannot be connected to an M904E Modutrol motor and to an ECM3000E control motor. Use the potentiometer for output to an external degree of opening indicator or the like. * Size C shows the length of the output...
